In the specific heat capacity experiment, the unknown object has a mass of 0.085 kg and was cooled to -6C. Then, it was placed in a calorimeter (mcalorimeter = 0.12 kg) that contain water (mwarter = 0.27 kg) at a temperature of 28 oC. After 5 minutes the temperature dropped to 23C. Determine the heat lost by the calorimeter. (cwater = 4186 J/kg. oC and ccalorimeter = 900 J/kg. oC)

In the specific heat capacity experiment, the unknown object was cooled, then placed in a calorimeter that contain water. The temperature of the calorimeter and water was measured using a temperature probe. The data was fitted using natural exponent function: 20.3+(24.7-20.3) exp(-t/0.51) Determine the ambient temperature.

A 25.0-g block of ice at -15.00°C is dropped into a calorimeter (of negligible heat capacity) containing water at 15.00°C. When equilibrium is reached, the final temperature is 8.00°C. How much water did the calorimeter contain initially? The specific heat of ice is 2090 J/kg ∙ K, that of water is 4186 J/kg ∙ K, and the latent heat of fusion of water is 33.5 × 104 J/kg.

In an experiment to measure the specific heat capacity of aluminium, identical size copper and aluminium blocks were alternately placed in an insulated calorimeter and heated by an electrical heater. The electrical heater supplied an identical energy E to the metal blocks. It was assumed that the heat loss (h) from both calorimeter measurements was identical. The measured masses were 530 g for the aluminium block and 1700 g for the copper block. The temperature rises were 15.3oC for the...
